De-verb in Reaper?
Hi!
I viewed a youtube-clip with Simon Larkin talking about an
interesting method to remove reverb from a recorded track
with just Reaper plugins:
https://www.youtube.com/watch?v=9c57YnS7ppA
I liked it and thought about making this without doing a
duplicate of the track. If I make 2 sends from the recorded
track like this:
Send 1 (Audio 1+2->Audio 1+2)
Send 2 (Audio 1+2->Audio 3+4)
Both sends go to a bus called De-Verb with Master send Checked.
(the recorded tracks Master send is unchecked)
Now when I phaseshift the Send 2 the sound will be canceled out....
I thought....but no, the recorded track plays thru.
If this could work my next step would be to put a compressor
on the insert on the De-Verb-bus and let the sound from 3+4
go thru it and let it manipulate the sound just like Simons
example.
However until I manage the cancelation after phaseshift it will not work.
Anyone have any idea why cancelation not work? It should...or?
Regards
TompaD

they cancel if you set both send and receivers to 1+2...
what is missing there is, insert the compressor on the submix track, set the detector to Auxilary L+R and there you have your receiving 3+4 from send 2

Cleanest way I can think of is:
Leave Master send on.
Make new track, call it Deverb Buss and send to it.
Flip the phase of either the receive or the track itself - no sound. Add the fast-attack compressor.
Then you can switch your Deverb Buss in and out by just muting the track.
It's a cute trick, but I think it's only really useful as an emergency rescue measure.

I think there is something wrong...because I got sound, its much less volume
but it still sounds.

Nevermind! I changed send to Pre-FX and now its no sound.
Thanks pepe44 and Jason! I go with Jasons example - nice and clean!

Better to use the standard Post-Fader Post-Pan send/receive setting. You just have to keep the fader on the buss track exactly at unity to get the phase cancellation.
With a Post-Post send/receive the Deverb buss will get everything you do to the original track.
For instance, with a Pre-FX send if you decide to add EQ or compression to the original track, it will play that altered version but the Deverb version will be using the uneffected version - so you won't get proper phase cancellation. The two waveforms have to be totally identical.
Actually. pepe's approach might be more flexible for use with multiple "deverbs" on different tracks.

...but when using Post-Fader the sound didnīt get canceled, I checked that faders was set to 0.00 on every place!

It works fine at this end. Try checking through your settings:
Master send on for both original track and deverb buss track.
Phase reversed on either the deverb buss track or the receive to it (not both).
Fader on deverb buss track set to unity.

Check!

Check!
...and I get decrease in volume only - no total cancelation. (With Post-Fader)
With Pre-Fader(Post FX) and Pre-Fader it works....
Itīs very strange - the laws of fysics dont apply to Post-Fader!

You skipped right over pepe44's first reply. The answer is in there.
Basically, it's easier if you just follow the video. Duplicate the track and put the compressor on the second, out of phase, track.

You can get SPL Deverb for $19 at Plug-in Alliance right now. Save a lot of effort.

I got it working with Jason Lyons example, I will test pepe44's example also.
But before that I wanna know why there is no cancelation using Post-Fader,
only when using Pre-Fader.

Yes maybe its easier following the video and duplicate the track,
BUT my intention was to see if it was possible to do without duplicated track.

Sure, but I wanted to test this effect with the plugins I already have.
And it worked - the question right now is why a track that I send to another
phaseshifted track (without FX) dont get fully canceled when I use Post-Fader
(but fully canceled when using Pre-Fader)

Does the attached help?
Whack a media item on the "Blah" track and try it out. There's a compressor on the "Dvb of Blah" track, but it's default-set, so success should mean total phase cancellation - ie silence.
If it doesn't work, I think there must be something going on with your preference settings.

Thanks Jason!
This works - very strange, because I have set up my channels exactly the
same way!
One other thing I feel is strange is that the meter on track Blah show -0.1
and the meter on track DVb of Blah show +1.4 - shouldn't both show -0.1??
(This is then I turn of the compressor and only checking the cancelation)

Ah good. Dunno about the metering issue - afaic, if you don't hear anything, it basically works. Plus, I haven't really played around much with the compressor settings to test the practical effectiveness of the idea.
As I said above, I think pepe's approach might be more useful if you want the flexibility to use multiple "Deverbs" with different comp settings on separate tracks. Probably worth exploring because you won't want the crispy attack/release you'd use on drums to apply to vocals or strings.
But if you just want a blanket approach to drain the soupiness out of one track or an entire mix, you can just buss it all into one like this.
Either way, transients are funny beasts - this is a useful idea, but it isn't a silver bullet...
As far as possible, I'd stick with the old wisdom - you can't unring a bell.
